Convenient synthesis of 4-amino-3,5-disubstituted pyrazoles in one step from the corresponding diketo oximes

A convenient one-step protocol for the synthesis of 4-amino-3,5- disubstituted pyrazoles has been developed. This method employs readily available diketo oximes as starting materials, and employs hydrazine hydrate for the cyclization and subsequent reduct

Stereochemical Assignments for 1-Phenyl-1,2,3-butanetrione 2-Oxime and Related Compounds

The 2-oximes of 3-methyl,3-ethyl, and 3-isopropyl-1-phenyl-1,2,3-propanetrione formed by nitrosation of the β-diketones exist preferentially in the Z configuration.For 3-tert-butyl-1-phenyl-1,2,3-propanetrione 2-oxime the (E)- and (Z)- oximes are formed in nearly equal amounts.An explanation for the steric effect of the tert-butyl group is suggested.
